Abstract: FIELD: road building machines. SUBSTANCE: working member has frame with deflecting shield and smoothing out plate on which two vibration bars are installed by means of two rockers and hinge supports. First vibration bar in direction of movement is placed between shield and smoothing out plate, and second bar, in slot of smoothing out plate. Rockers are installed for rocking in longitudinal plane by means of support hinge joint receiving alternate pulses from synchronously operating vibrators. For this purpose the latter are installed on top of rockers and are connected with engine by means of common shaft and flexible transmission. Vibrators are installed on rockers for obtaining greater effort on second vibrator bar than on first one owing to corresponding difference in arms of rockers. Each vibrator can be made with nondirectional-action unbalance weight to provide better effect and make the best use of capabilities of vibrator. In this case vibrator is installed on rocker to align vertical axis of vibrator in static state with vertical axis of support hinge joint. In dynamic state, "rocker-vibrator" system turns into swinging vibrator with driving force acting onto smoothing out plate under hinge support which turns this part of plate into additional compacting device of working member. EFFECT: creation of matched compacting forces on vibration bars which makes it possible to dispense with roller without increase in weight of proposed working member by disconnecting vibrator from frame. 2 cl, 2 dwg

Title: Active matrix electroluminescent display device
Inventor: HUNTER IAIN MCINTOSH
IPC: G09G3/20
Filed: 2002-12-18
Abstract: An active matrix electroluminescent (EL) display device comprises a matrix array of display cells (10) arranged in rows and columns, each cell comprising an EL display element (20) and driving circuitry. The cells are arranged in groups (12) which may constitute pixels. Each group of cells forms a series arrangement arranged so a data signal applied to the first cell in a series arrangement, via an associated data line (14), can toe transferred to a neighbouring cell in the same group, and so on for subsequent cells in the group, upon application of a control signal applied to an associated control line (15). This device enables a digital drive scheme to be implemented. The provision of grouped display cells arranged so as to be driven in this way enables a grey scale to be implemented using fewer data lines (14) than usual.

Title: Method of fabricating a tiered structure using a multi-layered resist stack and use
Inventor: GEHOSKI KATHLEEN ANN
IPC: H01L21/8232
Filed: 2003-02-20
Abstract: An improved and novel method of forming a tiered structure (10), such as a T-gate structure, including the fabrication of a stabilized resist layer (14) that provides for the prevention of interlayer intermixing with the deposition of subsequent resist layers. The method includes patterning a base resist layer (14) to provide for an opening (16) which will form the stem of the tiered structure and subsequently stabilizing the resist base layer without deforming the stem opening. Next, a resist stack (18) is deposited on an uppermost surface of the stabilized resist layer. Patterning the resist stack provides for an opening on an uppermost layer (22) or portion, and a reentrant profile in a portion of the resist stack adjacent the stabilized resist layer. Metallization and subsequent removal of the resist layers results in a tiered structure (32), such as a T-gate structure, formed using only low to medium molecular weight, linear polymeric materials such as those used in positive optical resists in optical lithography.
